According to Frank Fisher with the FBI, both Rodella and his son, Tommy Rodella, Jr., were arrested and are now in FBI custody.

The reason why both men were arrested has not been disclosed, but federal officials are expected to announce the filing of a significant federal indictment at the U.S. Attorney's Office at 11 a.m. Friday.

In June, FBI agents executed a search warrant at Rodella's home in connection to the arrest of a man who claimed the sheriff and his son chased him down in their vehicle, threatened him and then falsely charged him with aggravated assault on a peace officer.
